## ⥠Features
| Feature | Detailed Description |
| :--- | :--- |
| đĨī¸ **Cross-Platform** | Fully compatible with **Windows** (including Win 7), **Linux**, and **macOS** desktop operating systems. |
| đ¨ **Modern UI** | Based on Fluent Design, supports seamless light/dark theme switching and native High-DPI scaling. It also remembers the window position and size, restoring them on the next launch. |
| đ **Multithreading & Acceleration**| Native integration of multi-threaded parallel downloading, breakpoint resuming, and automatic network error retries for extreme download speed, plus a global speed limit option. Tasks that fail due to network errors are **automatically re-queued and retried** with increasing intervals and a visible countdown; this can be disabled or tuned in settings. |
| đ **Multi-Type Parsing** | Fully supports: `Standard Videos`, `Bangumi`, `Movies`, `Courses`, `Mall Courses`, `Interactive Videos`, `Audio (au/am)`, `User Space`, `Favorites`, `Weekly Must-Watch`, `Subscriptions`, `Watch Later`, `History`, etc. |
| đ **Batch & Search** | **Batch parsing** by pasting multiple standard video links at once; **keyword search** for User Space, Favorites, History, and Watch Later (filter the current page only, or search all pages); download items can also be **auto-selected** by preset conditions once parsing completes; parse history can be searched by title or link and filtered by content type. |
| âī¸ **Media Customization**| **Video**: 8K, 4K, 4K SDR Enhanced, HDR, Dolby Vision
**Audio**: Hi-Res Lossless, Dolby Atmos
**Codec**: AVC, HEVC, AV1
Preview exactly what will be downloaded before starting, with a clear notice of the actual codec when the selected one is unavailable. These options can also be adjusted directly in settings and are saved with your configuration. |
| đŦ **Danmaku & Subtitles** | **Danmaku**: `xml`, `ass`, `json`
**Subtitles**: `srt`, `lrc`, `txt`, `ass`, `json`
Customizable danmaku and subtitle styles, selectable subtitle languages, and `ass` danmaku/subtitles can be embedded into `mkv` containers. |
| đŧī¸ **Covers & Chapters**| Losslessly save covers (`jpg`, `png`, `avif`, `webp`), natively supports embedding posters directly into output video files (with an option to delete the original image afterwards), and can write video **chapter information**. |
| 𧊠**NFO Metadata** | Automatically scrapes and generates local media metadata formats complying with standards of media centers like **Kodi**, **Jellyfin**, and **Emby**. |
| đ **Classification & Naming** | Built-in powerful rule engine, with dedicated naming templates and multi-level directory classification modes for standard videos, bangumi, courses, interactive videos, favorites, user space, history, watch later, weekly must-watch, audio, and more. Naming rules are edited **visually**, and a single rule works for both single-part and multi-part videos. |
| đĻ **Format Muxing**| Smart audio & video stream mixing/extraction, supports output format to `mp4` or `mkv` to fulfill broad device compatibility requirements, with real-time progress during merging and conversion. |
| đ **Download Management** | The download list shows progress percentage and estimated time remaining, with tags for quality, codec, audio quality, format, and extra content; search by title, file name, uploader, collection name, or BV ID, and filter by status and media type â batch actions apply only to the tasks currently shown. |
| đĢ **Duplicate Detection**| Download history is recorded automatically, so downloading the same content again raises a prompt and can be skipped outright, saving bandwidth and disk space; items already downloaded are marked with a green check in the parse list. |
| đ **Network & Proxy** | Three proxy modes are available â **no proxy**, **system proxy**, and **manual configuration** â the egress region is detected on first launch to pick suitable CDN nodes, and User-Agent and Host are customizable. |
| đ **Clipboard Monitoring** | Automatically detects Bilibili links copied to the clipboard (including links copied before launch) and jumps straight into parsing and downloading after confirmation. |
| đ¤ **AI Client Integration** | Built-in **MCP server** (disabled by default) with HTTP and stdio bridge transports, letting AI clients parse links, create and manage download tasks, and specify per-task options such as quality, audio quality, and codec. |
| đ **i18n Support** | Built-in multi-language interface out of the box: Simplified Chinese, Traditional Chinese, and English. |
| đ **Secure Auth**| Supports quick and secure **QR Code Login**, **SMS Verification Login**, and **Cookie Login**. |
| đ **Open Source & Free**| Released under the **GPL-3.0** License, fully open-source, no in-app purchases, no ads, embracing community contribution. |
